Galapagois is the lead of Legends of Equestria's Public Relations team. He's also a writer and implementer for the project. His contributions include the seasonal events and their associated quests.
Galapagois is in charge of basically everything to do with the public front for Legends of Equestria. Favourited a tweet from the LoE account? He probably wrote it. Liked a Facebook post? Also him. Emailed the support address, read a news post on the website, had a sudden thought about horses in the middle of a non-horse-related day? He was behind them all.
Okay maybe not the last one, I might've exaggerated there. But you get the jist.
